DEVICE non RAISING an AUTOMOBILE WHEEL AND rromame rr IN ITS RAISED POSITION.

Application filed April 16',

The object of our invention is to provide a device for raising an automobile wheel and holding-it in its raised position, which device comprises an elevated'platform and an oppositely inclined runway arranged to first raise the automobile wheel as it rolls up the front'incline until the axle adjacent the wheel is brought to a position above the platform and then lower'the wheel as it rolls down the rear incline to direct the axle into position on theplatform for holding the wheel in its raised position. The'device more particularly comprises a folding platform and -a folding runway whereby they may be brought into a very compact and portable bundle vfor stowage when not' inuse.

A practical embodiment bf our-invention is represente'd in the ings, in which 7 Fig. 1 represents the device in top plan with the partsunfolded and in position for use. I Fig.2 represents a side VIGWOf the same.

I

The device consists generally of the runway for the wheel and the means for engag ing the axle to hold the wheel in its raised position, saidlmeans comprising generally I i the axle engaging platform and its folding support.

The axle engaging platform is denoted by 1, the to surface of which is preferably thereon. This platform is provided with the 1927- Serial No. 184,268.

depending side flanges 2, 2. The base 3 of the folding support fortheplatform 1 is provided with the uprising side flanges 4, 4. The pair of vertical side'members. 5, 5 are pivoted at their lower ends to the base 3 by depending flanges 2, 2 of the platform 1 when the parts are in their unfolded position. The lower ends of the pair of additional vertical side members 12, 12 are pivoted to the diagonal members 7, 7 by the connecting crossbar 13 and the upper ends of these additional vertical side members are pivoted'to the platform 1 'by the crossbar 14.- This arrangement not only'permits of a very rigid support for the elevated axle Awhen the partsare in their, unfolded osition, but also permits the parts to be folded. into a very compact bundle when not in use.

The rear .end of the base 3 is cut away and a traction wheel 15is mounted between.

the projectintg rear ends of the uprising side flanges 4, 4 or spacing the rear end of the base slightly above the ground or other sup port.

The runway comprises generally a base imd two oppositely inclined members as folows:

The runway base is denoted by 16 andits uprising side flanlgsby 17, 17. The front inclined member is denoted by 18 and its depending side flanges by 19, 19.

The lower front end of the said front inclined member 18 is pivoted to the front end w of the base 16 by a crossbar 20.

The back inclined member is denoted by 21 and its depending side flanges by 22, 22.

A crossbar 23 serves to hinge the u per rear end of the front member 18 to t e.upper frontend of. the back member 21. The lower-rearend of the back inclined member 21 is provided with a crossbar 24 removably seated in the open recesses 25, 25 in the ,u

rising flanges 17,

7 at the rearend oft e I base 16 for holding the parts in their operative position. By making the base 16 and the front .and back. inclmed members 18 and 21 of different widths, the parts ma be folded into a very compact bundle by. olding one inclined member within the other inclined member and then both inclined members within the base. The side flanges 17, 17 of the base are provided with open recesses 26, 26 and the-side flanges 19, 19 of the front inclined member are provided with two open corresponding recesses 27, 27 for receivingthe crossbar 24 when the parts are folded. To hold the runway against unintentional movement as the automobile wheel is rolled along the same, we provide depending projections 28, 29 at theopposite ends of the base 16.

We preferably make the front inclined member 18 of greater length than the back inclined member 21 so that when-the parts are in their assembled position, the front inits proper position at the side of the run-- way for receiving the raised portion of the wheel axle. The automobile is thenmoved to first cause the wheel to roll up the front inclined member of the runway for raisin the axle to a point above the platform an then roll down the back inclined member of- I the runway a short distance until the axle is brought to rest on the elevated latfqrmwith the wheel in its desiredraised) position.

7 The roller at the rear end of the platform "base permits a slight rearwardmovement of the platform as the axle comes into engagement therewith,'thereby preventing any possibility of the axle sliding off the platform as the wheel runs down the back inclined member of the runway. As-has been hereinabove pointed out, the downward projeetions on the runway base will 'prevent the unintentional movement of the runway ;arrangement of the several as the wheel rolls along the same. Y

From the above description it will be seen that we have. provided a strong. yet light device which will very easily raise the wheel 'to be manipulated and direct its axle into position to hold the wheel raised, said device being capable of being folded into' 'a very compact andportable bundle to be stowed away, in the automobile for instance, when notinuse.

It is evidentthat various changesmay be resorted to in the construction, form and arts without departing from the spirit an scope of our invention; hence, we do not wish to be limited to the particular embodiment herein shown and described, but

Whatwe claim is 1. lu a device of the character described, an elevated platform, a folding support therefor, and an oppositely inclined runway arranged, as a wheel is rolled up one incline and down the other, to direct the axle onto said platform, said folding support comprising a base, vertical members pivotally connected to the base, diagonal members pivotally connected to said vertical members and removably engaging the base, and additional vertical members pivotally connected to'the diagonal members and to the platform, the platform being removably engaged with the pivotal connection of said first named vertical members and said diagonal members 2.
